' 'This invention relates to a safety device for' clothes'wringers and particularly to a feeding means therefor,"whereby articles of clothing can be brought to the bite of the i press rollswithout danger tojthe' operator and-withoutany necessity ofthe operator.

bringing his hands into contact with the "rolls. V "The invention 1 objects a feeding device hav'ingia movable feed plate and a guide plate looselymonnted on a bell crank in such a position that they will raise clothes to the bite'of the press! clothing from 'being torn if it should become wrappedaroundtherolls; V

' A further important-object is to provide a device of this kind-wherein the upper edge of the feed platel will resilientlyhold-the' clothes against the upper roll over which it is drawn into-the pass between-therollsand which can yield tdthe thickness of the material being passed through-thewringer.

A further object is to provide a combination guidegand feedpla teto raise clothes to the biteof'the press rolls.

A stillfurther object to'provide a simple compact and efficient-device whichcan becheaply manufactured. '1' f h 1 v Figure 1 is a front View of-a wringer and invention thereon, having a section bro- I ken away showing'the mountingjof the parts.

I'In a more particular description of the parts,7 designates the usual metal wringer frame. having two uprights invwhich are I mounted the two wringer rolls 8 and 9 which-- are driven in a well known'manner. v Thus far the elements referred to embody well lrnownpartsof a power driven wringer.

My improved construction of a feeding 'de- 0 ice comprises bracket-members 10a and-10b;

which are mounted on the wringer frame; by; .1

screws-11, or such suitable fastening; The

' lowerportion of the bracket inemb'ersloa and." 106 have yoke bearings 12 in which is'loosely' 65 mounted a bell crank 13, the outward extended ends 14: thereof being used for operating handles." v V Extending across between the brackets 1062 isa guide plate 15 having itsinner edge near theiends'thereof loosely mounted on the bell crank at 16. i

'The plate 15 slopes downwardly towards the frontand' the front edge l7.thereof is bent downwardly on a radius from the bean ing 16. Extending'across the distance between the two'b rackets'lOa is a curved Verfeed plate conforms substantially to the ra-' dius'of the distance between the center of the 7 bell crank bearing and the upper edge ofthe feed plate 18. The upper longitudinal edge 7 of the feed plate 18 normally lies in front of 8 the guide plate 15, and is held in position by retaining plates20 mounted on theguide 15.-

b ing means for guiding the feed plate'18 V "inward toward the press: rolls. Figure'gis apart sectional View on line" A -1A, Figure2, and for convenience-I have shown a feedermounted on only one sideof' projection23 of the bracket member 1 0a.

When thegguide plate 15 is in its normal position the angle bends 22 bends 24.

:2In'orderto'resiliently urge the guide and V i i I w the bell crank13 inwalrdlytow'ard the lower mFig'ure 51mm enlarged section taken on 7 press rollflatsprings 25 are provided, one end Q lineB-B in Figure 1 and shows the'feed plate ofeach'heing secured tobracket 10a and 10b, 31

The upward extended'ends 21 ofthe gilide 9b 7 rest on theangleyQi the other ends of the springs bearing against the bell crank 13 at 26, resiliently holding the bell crank at its innermost position in link members 12. The feed plate is raised from a position shown in Figure 4 to a position shown in Figure 5; the forwardmost edge of the feed plate 18 can yield downwardly when it comes in contact ith the upper roll. If clothing is being fed through the wringer, the upper edge of the plate 18 may be depressed an amount equal to the thickness of the clothes so that the clothes will be resiliently held against the lower surface of the upper roll and drawn by the movement of the roll into the pass between the two rolls.

The bell crank 13 and the guide 15 are held in their innermost position in yoke bearings 12 by springs 25 and if clothes being fed through the wringer should become wrapped around the rolls the guide 15 may be moved outward thereby the amount equal to the thickness of the clothes so that the clothes will not become injured ther by.

lVhen the operating handles M are raised from a position shown in Figure 4 to the position shown in Figure 5 the feed plate 18 is rocked through. a corresponding arc. The rocking of the feed plate 18 also rocks the guide 15 when the lower edge 19 of the feed plate comes in contact with the edge 17 of the guide 15. lVhen the feed plate 18 is in its innermost position the angle bend 22 abuts the wringer frame 7 thereby preventing the feed plate 18 from being drawn into the rolls.

hen the feed plate and guide are in a refractive position shown inFigure4a portion of the clothes are placed on the guide. The handles 14 are raised and the forward edge of the feed plate 18 carries the clothes so positioned against the lower surface of the upper roll. The'elothes thus brought into contact with the lower surface of the upper roll are drawn into the pass between the rolls. hen the clothes are not bunched or when the material is relatively thin the plate 18 will yield only slightly,'but when the clothes are thick or are considerably bunched the plate 18 can be pressed forwardly against the springs 25 to an extent sufficient to permit such clothes to be dragged or pulled through the wringer.

In the accompanying drawings and description I have illustrated and described a pr fer-red embodiment of my invention, but it will be understood that the invention may be otherwise embodied and various changes and modifications may be in the structure thereof within the contemplation of my invention and under the scope of the following claims.
